Dual 5-Axis Mirror Milling
Horizontal mirror milling centers for aircraft skin production.
The Dual 5-Axis Mirror Milling series is designed for high-efficiency, high-quality machining of aircraft skins. With synchronized 5-axis milling and support heads, the system enables closed-loop thinning, wall thickness control and adaptive surface compensation.
Siemens and Heidenhain CNC control options.

High Efficiency
The system completes thinning, drilling, window cutting and edge milling in a single setup, helping reduce process steps and increase aircraft skin production output.
Closed-Loop Quality
In-process measurement, wall thickness feedback and adaptive compensation support controlled thinning, stable surface quality and repeatable machining results.
Digitalized Production
Process data, machine status and quality information can be monitored and visualized to support traceable, manageable and automated skin production.
Green Economy
Mirror milling reduces the need for chemical milling, supports aluminum chip recycling and enables a cleaner, lower-emission production environment.
